Abstract (en)
The present invention encompasses an apparatus and method for a wireless communications device to choose the optimum wireless data network from a plurality of network choices. The wireless communications device employs a protocol converter to convert out-bound data messages to a format usable by the wireless data network chosen and convert in-bound data messages to the original format usable by the wireless communications device. Based upon radio frequency measurements from a plurality of wireless data networks in the current coverage area, the protocol converter will instruct the wireless communications device to communicate on wireless data network with strongest radio signal strength indicator or a user-preferred wireless data network where the minimum radio signal strength indicator requirement has been met. For end-user terminal transmission of data messages, the protocol converter will perform conversion of data messages to the current wireless data network and then transmit the data messages via radio frequency transmission to the wireless network s base station. Also, upon reception of data messages via radio frequency transmission from the fixed-end terminal, the protocol converter will perform necessary conversion of data messages to the format usable by an end processor of the wireless communications device. <IMAGE>
